Vagrant tutorial

Monday:

Vagrantfile: created in ruby Split into various functions to call as it provisions the box - options on config.yaml

Vagrantfile

if File.file? "#{filename}.json"
    machines = JSON.parse(File.read("#{filename}.json"))
else
    machines = YAML.load_file("#{filename}.yaml")
end

Checks if the filename variable json exists (default "config") and uses that for vagrant configuration, else uses a yaml.

Rest of the Vagrantfile loops through each machine, calling functions iteratively to set the various options.

Config

Contains various config options; The following is in yaml, however there is the option to use the exact same options in .json (the only difference is notation as opposed to naming)
